Da. Plier et al., T-LYMPHOCYTES FROM INDIVIDUALS WITH FILARIAL INFLAMMATORY DISEASE HAVE INCREASED TRANSENDOTHELIAL MIGRATION IN-VIVO, Clinical immunology and immunopathology, 82(3), 1997, pp. 216-220
The in vitro transendothelial migration of circulating filarial antige
n-specific T-cells was examined in Wuchereria bancrofti infection. Cir
culating T-cells from individuals with filaria-induced lymphatic patho
logy (LP) had significantly greater migration through unstimulated HUV
EC monolayers than did T-cells from asymptomatic infected (MF) individ
uals (P = 0.04). In contrast to the MF individuals where no effect was
seen, transendothelial migration of 48-hr filarial antigen stimulated
T-cells from LP individuals was significantly (P = 0.01) greater than
migration of 48-hr media-stimulated T-cells. In six of seven patients
examined, inhibition of the VLA-4/VCAM-1 pathway resulted in greater
than 50% inhibition of transendothelial migration of T-cells. (C) 1997
